My dresser cab is nearly done but I need some exhaust. It is 37in x 30 x 18 and I am planning on using about 8 23w CFLs. Right now I am setup in my bathroom and temps are peaking at 82.

Any cheap suggestions would be appreciated. I have thought about PC fans but not sure if that will be strong enough to pull through a carbon filter. Was looking at this http://www.homedepot.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10051&langId=-1&catalogId=10053&productId=100067594 or something similar.

This is the last thing I need to get installed so any help +rep!

Thanks for the quick reply. I was hoping for something a quite bit cheaper but if its quiet and gets it done then I guess this is the best bet.

Consider this fan. Its the quietest fan on the market. If you need to just put two in. It runs off a magnetic bearing so there's no motor noise, just the air. i've used them myself because i build PCs.

I am a little concerned that the PC fan wont pull through the carbon filter very well. This fan http://www.lowes.com/pd_185009-1061-DB206_4294933130+4294836901_4294933768?catalogId=10051&productId=3089845&Ne=4294933768&currentURL=/pl_22_4294933130+4294836901_4294933768_&N=4294933130+4294836901&identifier=22&langId=-1&storeId=10151&ddkey=http:CategoryDisplay is cheap and local. I think I am going to go by and see if is too loud. The valueline is probably the best but at $70 plus shipping its a little steep. I am already a bit over budget on this project. If anyone else has some input on whether or not this is a good idea or other cheap alternatives I am interested.

picking up my duct fan today. Hopefully it works well. Its more powerful than a couple pc fans but that valueline is pretty sick. If this doesnt work out then when I get some more cash I am going to spring for it. my box is very small so I am hopeful.

well I have the thing kind of stuck in there at the moment and I dont know if its pulling enough air. It says its supposed to be a 210 CFM fan and it seems to be sucking quite a bit but not alot is coming out. Ill include a pic, but be warned I have no idea what I am doing and so its pretty ugly. I read that hanging the fan will take out some noise, which is what I have done.

Well, got everything in there and ran some temp tests. I think it may just be too hot in my neck of the woods. Temps were 97 in the box during a day test run with no plants. It was about 88 in my apartment today with the humidity factored in. The room I grow in has very little circulation from the AC and I think this is the primary factor. There is no way I can cool this box without some sort of mechanism that actually lowers temperature.

Thanks for the tips everyone. Back to the drawing board. I am still interested if anyone has any ideas on how to cool this thing down. I added two more fans for circulation and to draw from my intake...
